516 The Inconstancy of Fasciated Races. 
In the summer of 1895 I isolated some of the atavists 
of my race of Crcpis bicnnis described above, before they 
flowered. 1 The seeds were sown in the following year 
and produced over 350 plants. About 20% of these ex- 
hibited the comb-like structure in the center of the ro- 
settes, and this line sometimes reached a length of five 
centimeters. Thus we see that the seeds of the atavists 
may produce fasciations in about the same quantities as 
do the selected fasciated individuals. Inasmuch as the 
monstrosity frequently lowers the strength of the plant, 
it might perhaps even be advisable to choose the seeds 
of the atavists or of individuals which are only fasciated 
on their lateral branches. 
A further proof of the view that the atavists are only 
fasciated individuals with their character in a latent con- 
dition is afforded by experiments on the effect of thor- 
ough manuring. For the individuals which under normal 
favorable circumstances behave as atavists can be in- 
duced by it to a relatively considerable development of 
fasciations. In 1895 I made such an experiment with 
my strain of Crcpis biennis fasciata which then contained 
some 20 to 40 % of fasciated individuals every year. I 
manured a group of 41 plants with an abundance of horn- 
meal. At the time of ripening only six of these lacked 
the anomaly, i. e., 85% instead of 40% were fasciated. 
The plants stood fairly close together, at distances of 
about 20 centimeters apart. If I had given them enough 
room I should probably have succeeded in inducing the 
anomaly in every one of them. 2
